Time Domain Bucking Circuit

[bklein]

I came across this article in a search. It indicates a means using a gyrator circuit to allow sooner pi fly back signal sampling. I think the pulse response is identical to a no target response and then you differentiate to detect the target signal. Anyway, can someone obtain the article for me? It is posted at several sites but all require membership. Is this how the AQ does it?

Hi bklein
If you also believe that the time-wise knowledge monopoly the whole journal publication system imposes is wrong and a brick-wall hindrance to the dissemination of humanities knowledge, especially to third-world countries, then use Sci-Hub to download it yourself.
We have the local university here now unable to purchase the latest journals due to the over inflated costs these parasites impose. We have medical research establishments unable to keep up with the searing edge and funds being bled off by these leeches.

The whole journalistic system with its buddy peer review process is broken and I use Sci-Hub more so as a protest against the elitism and snobbery of academia.
But before you do this, make sure you are aware that you are considered to be stealing, even though the system is elitist, draconian and morally wrong.

If Sci-Hub is down, this site can usually point you to a working mirror http://www.novoprolabs.com/support/a...606101263.html

I posted this link a while back. It's not the whole paper but gives some details.

Yes that is the article that I first saw. Maybe it is the gist of the paper too as it is only a few pages. I’m going to try and contact one of the authors directly.

Someone good with LT spice could try a simulation. It could be simple as an inductor in place of the damping resistor which is connected to ground when the pulse is switched off? Or a gyrator which can be tuned. The inductor would probably need to be equal to the coil inductance to absorb the flyback energy?

I tried a gyrator circuit like described in the teaser article and it was very similar response as the fly back - but you have to tweak everything in your design to make it work.

The gyrator circuit may be replaced by a simple coil, provided its L/R is better than the search coil. Only Antoniou gyrator will perform better than a real coil anyway.
